What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Granby building permit application.
Understanding REScheck and COMcheck
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Granby project needs depends on whether the work is residential or commercial — here is how they differ.
What is a COMcheck?
COMcheck handles commercial work and high-rise residential of four stories or more. The DOE tool evaluates envelope, lighting (interior and exterior), and mechanical systems against either the IECC or ASHRAE 90.1, with trade-offs allowed across components.
What is a REScheck?
REScheck is the DOE’s residential compliance tool. It covers one- and two-family dwellings and low-rise multifamily (three stories or fewer), using a UA trade-off so a stronger wall or roof can make up for a weaker window while the overall envelope still meets the IECC.
REScheck Projects in Granby
REScheck is the simplest path for smaller residential projects in Granby that do not trigger a full performance-path energy rating. It is typically the right tool when your project is:
- New residential construction or an addition under 1,200 square feet that does not require a HERS rating
- Finished basements, attic conversions, and dormer additions on existing homes
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Detached accessory structures with conditioned space
- Additions, alterations, or renovations to a one- or two-family home
When Do You Need a COMcheck in Granby?
COMcheck is required for commercial and larger projects in Granby. Reach for a COMcheck when your project involves:
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Restaurant build-outs and retail white-box improvements
- Medical, dental, and professional office construction
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
